Python CSV，使用 CSV 将多列合并为一列

Question

我一直在想办法将我拥有的 csv 中的所有列合并为一列。

import csv
with open('test.csv') as f:
    reader = csv.reader(f)
    with open('output.csv', 'w') as g:
        writer = csv.writer(g)
        for row in reader:
            new_row = [' '.join([row[0], row[1]])] + row[2:]
            writer.writerow(new_row)

这可以合并前两列，但我一直无法尝试将其循环并将其余列合并为一列。

Answer 1

您应该将 row 传递给 .join，因为它是一个数组。

import csv
with open('test.csv') as f:
    reader = csv.reader(f)
    with open('output.csv', 'w') as g:
        writer = csv.writer(g)
        for row in reader:
            new_row = [' '.join(row)] # <---- CHANGED HERE
            writer.writerow(new_row)
